I. The Sources of Morality

From The Catechism of the Catholic Church

1754
The circumstances, including the consequences, are secondary elements of a
moral act. They contribute to increasing or diminishing the moral goodness or
evil of human acts (for example, the amount of a theft). They can also diminish
or increase the agent’s responsibility (such as acting out of a fear of death).
Circumstances of themselves cannot change the moral quality of acts themselves;
they can make neither good nor right an action that is in itself evil.
